[FIXED] How to get an ENV var available in project which uses Android.mk

Issue

I have an Android project which uses Android.mk files for the setup. I would like to introduce Build Variants to the project and based on a build var such as BUILD_BRAND to perform some UI changes.

My case is: I have BUILD_BRAND exported on my Ubuntu in the .bashrc. If I echo $BUILD_BRAND I would get the value printed in the terminal.

I also do $(warning $(BUILD_BRAND)) and I can see during the build the value is printed so it is available.

But when I try to do System.getEnv("BUILD_BRAND"); in an activity, a null is returned.

The question is how to make this value under BUILD_BRAND to become globally available to the project.

Thanks!

Solution

In my case the solution was to use SystemProperties.get("the.property.name").

The "the.property.name" was set in the Makefile.mk located in the core.

I also find out that I can export ENV vars to the project during build time using the same Makefile.mk.

N.B - You can't access an env var during runtime directly using System.getEnv() !
